Recently my tabs and tool bar color scheme all turned white. I have gone through Add Ons and Themes and changed/enabled the default, as well as other color themes. The tabs still don't appear properly. They all blend together, whereas previously I could see an outline for each tab. I then wanted to uninstall firefox and then install it again. The problem I am having is that when I go to install it (after downloading it again), it recognizes I previously had it installed and it only allows me to install it again with whatever is left behind from the previous install. My PW, History, Login, etc., are still present on the new install. My question..... How can I install FireFox and have it be complete new? I don't want any previous info on there. Something has messed with my application internally and I don't know how to isolate it and would prefer a completely fresh slate. I believe my PC is operating Windows 10. I have been using the same system and Firefox on this PC for 4 years now, without previous issues. Thank you.

Bonjour, Suite à la dernière mise à jour de Firefox, j'ai sans cesse le message d'erreur VCRUNTIME140_1.dll introuvable. Conseil de réinstallation de l'application etc. J'ai beau faire une désinstallation complète et un nettoyage puis une réinstallation, rien n'y fait. J'ai toujours le même message depuis plusieurs jours. Et c'est énervant ! Je suis obligé de naviguer sur Edge et je n'aime pas du tout. Merci de m'aider. Bonne journée. Philippe

I use Firefox for more 11 years and it is the first time i have problem to begin Firefox after last update processus. A message annince that XPCOM file is not there and Firefox can't go on.

I had to use an another platfom to Install integrally Firefox... a shame ! The problem is solved but It is a very bad new : Firefox update aren't safe now !!!

I hope the next update Firefox work correctly.

Has Mozilla be aware of this new problem ?

What setting will stop the constant notice "Download the latest version of Firefox." I don't want 20 notices per day. It's like having a child in the backseat "are we there yet?" "are we there yet?" "are we there yet?" How many times do I have to click the "Dismiss" button before this stupid software understands that I do not want updates? I've noticed that this is a common complaint. Stop the bullying by making people choose automatic updates. Many times things get messed up on my computer with updates and it is not worth the aggravation. Candace M.

I was using Firefox this morning, and the program crashed. When I restarted, I found I had lost all my passwords. I searched for the "Old Firefox Data" folder on my desktop--and everywhere else, and there is no such folder on my computer. I tried importing passwords from Safari and that didn't work at all. I am traveling right now and don't have access to my backup disk.

This is the second time this has happened with FF, and I am about to dump the program because of this.

Any ideas?

Moonfruit.com are telling customers to install a version of FF that apparently has a fix for their issue with flash. I am concerned this will compromise the browser & security... can anyone confirm if this is safe / OK to do?

Copied from their instruction pdf:

Hello, Genius Folks.

As I am using an HP Chromebook 11 G3 with my work and needed to install firefox to use one of our tools, however, I cannot find the right solution to download and install it. I google all the possible ways but there is missing in the steps and I cannot find it in my Chromebook,

There is a step I need to go to Settings >> Advance >> Developers >> Turn on Linux. But my laptop's settings are not showing me any "Developers" option.

Would there be anyone who can help me in this scenario? Or someone who experienced this?

Thanks in advance! Honey,

Hi: Can anyone help me to recover BOOKMARKS which I've found missing after today's starting my Firefox Browser/Thunderbird and trying to use one of the BOOKMARKS: this is for the first time I've lost them just by opening the Program after I've about 3 weeks ago Upgraded my Windows 7 to Version 10 - under Windows 7 they were working properly without any 'accidental loss'. Question: - is it possible to use the Bookmarks-Back Up file to re-install them - IF NOT, what is the other way to reliably re-install them ...? My PC-system is: Windows 10 Home, Ver 10.0.19042 (20H2), CPU; Intel Pentium D 935 3.20Ghz (dual core), x64-based processor, 32-bit. I'd greatly appreciate any SPECIFIC INSTRUCTIONS how to accomplish this. Tony H.

I work with a site from where I can download content only from a pop up window, but when I do click on the download it does not show progress. However, in my regular window(non pop up) when I download any content I see the download progress. Is there a way to enable download progress icon in the pop up window toolbar?

Firefox 89 crashes almost instant, even in safe mode. Which I didn't know existed until this trash version. After downgrading back to 88. I have no tabs, no bookmarks, no extensions. Needless to say. Livid.

I have an older windows XP laptop system. I had to restore it to factory settings and lost all of my browsers. I can't get on any web site to download any browsers to the XP system. Is there a way to download to a USB drive from my windows 10 desktop and install it on the XP system from the USB drive?

I have turned off auto updates due to the new version of firefox replacing 88.0. I do not need to change the color of the title bar, nor do i need everything i type in the search bar in the center of my screen to be mirrored in a search bar located in the title box. How do i get security updtaes without all the screen changes in 89.0

The 89.0 (64-bit) update to Firefox is a joke! When are fixes coming or is there any way for me to return to the previous edition. I cannot get used to this charade.

I think that Firefox is by far the most superior browser and this update is just so not Firefox. It hurts. It hurts really bad!
